Given numbers are 215, 660, 230, 973

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 230 are 2 x 5 x 23

Prime factors of 973 are 7 x 139

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 215, 660, 230, 973

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(215, 660) = 28380

GCD(215, 660) = ( 215 x 660 ) / 28380

= 215 / 660

= 215

Step2:

LCM(5, 230) = 230

GCD(5, 230) = ( 5 x 230 ) / 230

= 5 / 230

= 5

Step3:

LCM(5, 973) = 4865

GCD(5, 973) = ( 5 x 973 ) / 4865

= 5 / 973

= 5

So, Greatest Common Divisor of 215, 660, 230, 973 is 1
